Hospital sewage contains pathogens, heavy metals, disinfectants, organic solutions, acids, alkalis, and radioactive materials. Hospital sewage treatment is mainly disinfection, that is, killing pathogens. A common method is chlorine dioxide disinfection. How to choose a chlorine dioxide generator for hospital sewage disinfection equipment is very important.

    1. Raw material cost:

According to the different costs, we have arranged the different disinfection processes in ascending order. They are: liquid chlorine, sodium hypochlorite generator, chlorine dioxide generator, ultraviolet rays, and ozone.

    From this we can see that the cheapest sterilization process is using liquid chlorine, the second is a side-by-side sodium hypochlorite generator and a chlorine dioxide generator, and the last two are ultraviolet and ozone. Among them, although the cost of using liquid chlorine is relatively low, we cannot ignore one problem, that is, liquid chlorine is a dangerous chemical, it is not easy to store, and it risks leakage and explosion during use, so we do not recommend it. use.

    The second sodium hypochlorite generator and chlorine dioxide generator are recommended by us, so the cost of using these two equipments is basically the same, but the sodium chlorite generator uses the electrolytic salt water process. The raw materials of the chlorine generator are relatively easy to buy, and they are also cheap. They only need a certain amount of electricity. For the last two types of UV and ozone, the cost of these two types of equipment is very high, and ordinary hospitals cannot afford them, so they can be ignored.

     2. Bactericidal effect:

In the comparison of sterilization and disinfection effects, the sterilization effects are: ozone, sodium hypochlorite generator, chlorine dioxide generator, liquid chlorine, and ultraviolet light. Among them, ozone has the best sterilization effect, followed by sodium hypochlorite generator and chlorine dioxide generator, and finally liquid chlorine and ultraviolet rays. Ozone sterilization has the best effect, but the cost-effectiveness of ozone sterilization is not high under the constraints of the use cost, so it is not recommended.

    The second and third sodium hypochlorite generators and chlorine dioxide generators have significant sterilization and disinfection effects, and the cost of use is not high. Therefore, we recommend everyone to use sodium hypochlorite generators and chlorine dioxide generators. Liquid chlorine sterilization is currently being phased out, and the instantaneous UV disinfection is good, but it cannot guarantee a second relapse, so it is not recommended.

    From the perspective of comprehensive use cost and sterilization effect, the best sterilization effect is the use of sodium hypochlorite generator and chlorine dioxide generator. These two devices have reliable sterilization and disinfection effects, and the use cost is very low, which is very suitable for tight budgets and Used in hospital sanitation facilities where large quantities of sewage need to be treated.
